(This is the Warren Buffett Watch newsletter, news and analysis on all things Warren Buffett and Berkshire Hathaway. You can sign up here to receive it every Friday evening in your inbox.) Berkshire Hathaway shares managed to set a few more all-time highs in an otherwise lackluster week of trading. The Class A stock closed Monday at a record high $821,931 but ended the week up just 0.3% at $815,600. It spiked at Friday's open to almost $822,929, but that wasn't enough to top its record intraday high of $824,765 set on Thursday of last week as Berkshire entirely erased what turned into a 15% pullback after Warren Buffett announced last year that he would step down as the company's CEO .
